Quick and efficient: Since PEBs are mainly formed of standard sections and connections, design time is significantly reduced. Basic designs are used over and over.

Slow: Each conventional steel structure is designed from scratch by the Consultant, with fewer design aids available to the Engineer.

Average 6 to 8 weeks.

Average 20 to 26 weeks.

Simple design, easy to construct and light weight.

Extensive, heavy foundations required.

Both costs & time of erection are minimized.
The erection process is easy, fast, step by step and with hardly any requirement for equipments.

Typically, they are 20% more expensive than PEB. In most of the cases, the erection costs and time are not estimated accurately.
Erection is slow and extensive field labor is required. Heavy equipment is often needed

Outstanding architectural design can be achieved at low cost using standard architectural features and interface details.

Special architectural design and features must be developed for each project, which often require research and thus resulting in much higher costs.

PEB Building are designed with future expansion in mind. It is simple, easy and cost effective. One supplier can co-ordinate changes.

Future expansion would be more difficult and, more likely, costlier.

Single responsibility for design, supply and even erection of PEBs.

Multiple responsibilities can result in questions of who is responsible when components do not fit properly.
